ASM G2 not working properly

hqgc · #1 03-18-2007, 09:05 PM

Once my G2 hits max capic. after 3 or 4 days , that seems to be it. I am starting to wonder if it has to do with the "crud" that builds up at the top of the riser tube. Once it gets too "brown" and thick around the top that seems to be it, the skimmer stops producing. Its like that crud prevents anything from going over the top into the collection cup.
Does this sound familiar Tony and cprowler?

I get the band of crud around the top as well, seems to have no effect, though when I empty the cup, I usually wash off.

Hmm, interesting. I'll have to watch for that effect. It could be happening for me. But it's hard to say. Usually the skimmer works better after I've emptied and cleaned the cup, which could be explained by the crud preventing the foam from spilling over, but then I usually give the venturi a quick clean as well at the same time so it's hard to say, maybe the better initial performance is because of that instead.

Interestingly this last week I've gotten a half cup full of skimmate. It hasn't performed so well in months. Maybe it's heard me talking about the mods I'm going to make on it and it's trying to shape up

Honestly I do find that the venturi is very sensitive. Just a quick poke through with a nail is all I do at cleaning time, takes basically 10 seconds and it ensures there is no blockage starting. Give that a try maybe?

The venturi.... is that part where you hook the air tubing?
I think I will start threatening mine with some mods as well.

Yep .. that's the part. I slip the tubing off, take a nail and push it into the hole, wiggle it back and forth a few times and replace the tube. It's a bit of a pain because it's really tight in my sump but it seems to be worth the effort.

Must have something to do with either the Ca levels are where kalk or reactor effluent is added.

Never had a blockage in the year+ my G3 has been up and the only maintenance I do on mine is to dump and rinse the cup and then every few months take the skimmer out of the sump and hose out the skimmer body and run some water through the airline.
